An ovenable bag includes a sheet of paper-like material; opposite edges of the sheet secured to each other to define a tubular member having opposite ends; the tubular member being folded inwardly along lengthwise fold lines thereof which are diagonally offset from each other and being flattened with respect to the lengthwise fold lines to form two pair of lengthwise crease lines that are parallel to the lengthwise fold lines, such that the flattened tubular member is defined by a wide wall section, a narrow wall section and an expandable wall section connecting the wide and narrow wall sections together; the narrow wall section extending past the wide wall section in the lengthwise direction of the flattened tubular member at a first end thereof; the flattened tubular member being folded over itself at the first end thereof along a transverse fold line; the wide wall section being adhered to itself at the folded first end of the flattened tubular member; and the narrow wall section being adhered to the expandable wall section and the wide wall section at the folded first end of the flattened tubular member to provide a liquid seal at the folded first end of the flattened tubular member.
